The lens in the adult human eye blocks nearly 100 percent of the sun's UV rays. As part of the normal aging process, the eye's natural lens eventually blocks some short-wavelength blue light as well â the type of blue light most likely to cause damage to the retina and lead to macular degeneration and vision loss.
Because the light is exiting the fiber in a cone-shaped beam, your eye cannot focus it on the retina. This is unlike the typical lab laser or laser pointer that shines a narrow, collimated beam that does not spread out; a beam your eye can easily focus on the retina, causing temporary blindness.
